INJECTOR-BURNER.

SPECIFICATION forming part of Letters Patent No. 784,505, dated March '7', 1905.

A hcmion filed December '7, 1903. Serial No. 184,122.

To all whom it may concern:

Be it known that I, ALLAN C. RUSH, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented certain new and useful Improvements in Injector-Burners, of which the following is a specification.

This invention relates to positive and extremely eflicient means for utilizing liquid hydrocarbons as fuel.

The primary object of the invention is to provide a burner which, while extremely durable, shall be very positive and efficient in operation and in which all liability of clogging or choking the burner by carbonization will be avoided and which shall be particularly adapted for use with crude hydrocarbon oils such, for instance, as the heavy crude asphaltum oils of California.

A further object of the invention is to provide a burner which is adapted to furnish a sheet of flame either circular in form or in any desired arc of a circle and in which the body of the flame may be of any desired depth, according to the requirements of the particular apparatus with which it is used, so that the burner-body may with very slight expense, either of time,-attention, or material, be readily adapted for various uses, from that in which a circular flame is desired to that in which a flame is desired to be projected in a given direction or are of a circle and in which the body of the flame may be regulated at will.

A further object of the invention is to provide suitable means by which the amount of flame generated by the burner may be entirely within the control of the operator and the area thereof may be positively and readily regulated by the operator from without the lire-box, as desired.

Other objects and ends in view will hereinafter appear from the detail description of construction and operation.

To these ends the invention consists, primarily, in a body having an annular channel, the outward wall of which terminates in a plane, and I provide means for supplying liquid fuel to said channel, means for directing an expansive fluid from the interior outward radially across said channel in a plane parallel to said terminal plane, so that when the channel is unobstructed a circular flame may be produced and by temporarily closing a portion of the channel a fan-shaped blaze may be produced; also, in providing means whereby the operator from outside the lirebox may readily regulate the depth of the flame.

The invention consists, further, in the provision of an air-chamber surrounding the oilpipe and extending outside the furnace and communicating air to the burning liquid fuel at the point of projection thereof into the lirebox, the air-chamber serving not only to supply atmospheric air to the burning vapor, but also as a means to prevent too great superheating of the oil in the oil-pipe; also, in the provision of means whereby the amount of air supplied by said chamber may be controlled and the delivery thereof regulated as desired.

The invention consists, further, in various constructions and in general and specific combinations of parts, all as hereinafter described, and particularly pointed out in the claims, "and will be more readily understood by reference to theaccompanyingdrawings, forming a part of this specification, and in which- Figure I is a side elevation of an injectorburner embodying my invention.

Fig. XVI is a longitudinal sectional View of my three-way coupling for the oil-pipe and the packing-gland I employ about the steam pipe passing through the coupling.

As shown in the drawings, 2 designates the atomizer-bod y, which is preferably in the form of an L and hollow and into one end of which screws the oil-pipe 3. The body 2 is cored out to provide the two chambers 4 and 5, whichare respectively for the oil and steam,the chamber 4 surrounding the chamber 5. The steam pipe6 screws into the ends of the wall of the chamber 5, the pipe 6 being within the pipe 3.

The body 2 is preferably cast with a top plate 7 integral therewith. This plate 7 is provided with a central opening through which the lower end of hollow plug 8 passes to screw into the top end of the wall of the chamber 5. The top plate 7 is also cut away to form a curved or arc-shaped passage or duct 9, forming the outlet from the chamber I.

The hollow plug 8 is provided with a shoulder 10, adapted to seat on a seat 11 on the top plate. The hollow plug 8 is provided with one or more peripheral ducts or outlets 12, leading from the chamber of the plug above the top plate 7 and horizontally across the plane of the oil-outlet 9.

13 represents a segmental ring provided on its under side with a bead 14, adapted to rest in the duct 9 and in a groove or channel 15, formed in the top plate. The cut-away portion of this segmental. ring determines the width or are of the flame projected by the burning intermingled steam and liquid fuel.

16 represents a sleeve adapted to be screwed onto the upper threaded end or shank of the hollow plug, as shown. This sleeve is hollowed out at its lower end to form a central chamber, the inner end of the chamber being of suflicient diameter to permit the sleeve 16 to be screwed down, so that the lower end of the sleeve 16 comes below the plane of the bottom of the port or ports 12. A suitable expansion-chamber 17 is formed within the lower end of the sleeve 16 by increasing the diameter of the central chamber of the sleeve, as shown. It is thus seen that the outlet of steam from the chamber of the hollow plug is through the port or ports 12 into the expansion-chamber 17 and thence out through the annular duct or passage 17', formed between the lower edge of the sleeve 16 and the upper face of the top plate 7. In order to provide means whereby the flow of steam from the chamber of the plug 8 into the expansionchamber 17 may be regulated to agree with the regulation of the segmental ring 13, I providea secondary segmental ring 19, adapted to seat upon the top face of the top plate 7 and provided with a vertical flange adapted to extend into and close that portion of the expansion-chamber 17 which it is desired to cut out of'service.

20 is a deflector which, as shown best in Fig. IV, is in the form of a sleeve adapted to be slipped over the sleeve 16 and provided with a horizontal flange 21. The flange 21 is provided with a series of holes 22, through which bolts 23 pass into the rim of the body 2, holding the sleeve 20 in place on the body 2. As shown in Fig. II, the bolts 23 also pass through the segmental ring 13. thereby holding the ring 13 fixed in place. The outer periphery of the upper end of the sleeve 20 is threaded and adapted to receive'the cap or cover 24, adapted to be screwed into place thereon. shown in Fig. II, the sleeve 16 is held in the desired position over the hollow plug 8 by a lock-nut 25.

The body 2 is provided with an opening in its wall leading into the chamber I, through which access may be had to the chamber 4 for the purpose of cleaning the same when desired. This opening is normally closed by a plug 26.

In Figs. VII to XIII of the drawings I have shown my burner provided with means whereby the width of the flame, as well as the thickness of the body of the flame, may be regulated at will by the operator from outside the fire-box' or furnace in which the burner is used. In order to accomplish these results, I make the segmental regulating-ring in two parts 13 13". The part 13 is cut away so as to provide a horizontal flange 13, having on its under face a series of teeth 13, and the part 13 is cut away, as shown, and provided on the upper face of the horizontal flange 13 formed by the cutaway, with a series of teeth 13. The flanges 13 and 13 as shown, extend one above the other. The two parts or segments 13 13, forming the segmental regulating-ring, in this form of my burner are adapted to be revolved. so as to increase or decrease the free or unobstructed portions of the channel 9 and steam-discharge slot 17, formed between the upper faces-of the top plate 7 and the edge of the sleeve 16. heads 14 of the segments 13 13 extend into the channel 9 and the parts 13 and 13 operate to shut off the exit of steam through the steam-discharge slot 17', it is obvious that the movement of the two parts or segments 13 13 toward and away from each other regulates the portions or lengths of the oil-duct and steam-discharge slot 17, through which oil and steam may be emitted, and by such As the movement of these segments or parts the latteral adjustment of the width of the flame is eflectuated.

27 represents a rod which forms the means extending from within the reach of the operator outside the fire-box or furnace into connection with my burner and by which the movement of the segments 13 13 is controlled. As shown, the body 2 of the burner is provided with a vertical flange 28, through an opening in which the rod 27 extends.

29 represents a plug in said opening adapted to take up any wear.

The inner end of the rod 27 is in the form of a bevel-gear 30 and meshes with the teeth 13 and 13" of the segments 13 13., respectively. By rotating the rod 27 the desired movement of the segments 13 13' is accomplished. The rod 27 has a bearing in the standard 31, provided by-a vertical flange rising from the body of the burner. The other end of the rod 27 has a bearing in the standard 32 outside the fire-box or furnace, this standard 32 being either formed integral with the pipe 3 or in any other desired manner. After passing through its bearing in the standard 32 the rod 27 passes through a gage plate or dial 33, which may be formed separate or integral with the standard 32, as desired.

On the outer end of the rod 27 I provide an operating or hand wheel 34, by means of which the rod 27 may be revolved, and in connection with such hand-wheel an indicator or pointer 35, operating in connection with the dial To provide the means whereby the vertical depth or volume of the flame may be regulated by the operator or attendant from without the tire-box or furnace, the sleeve 16 is provided on its periphery with gear-teeth 36. As shown in Fig. VIII, these teeth only extend down the periphery of the sleeve 16 far enough to permit the desired range of regulation. An operating-rod 37 has on its inner end a worm 38, which meshes with the external gear of the sleeve 16. This rod 37 also has hearings in the standards 31 and 32 and is provided with an operating or hand wheel 39, pointer 40, and dial 41, similar to the operating-wheel, pointer, and dial provided in connection with the rod 27.

\Vhen my burner is provided with means for adjusting the sleeve 16 vertically from without the fire-pot or furnace instead of the cap 24, as shown in Fig. II, I provide a cap 42, having a chamber into which the upper end of the sleeve 16 extends and through the top of which the end or shank of the plug extends.

The flange 44 of the cap rests upon the rim of the standard 28. h

In order to supply the requisite atmospheric air from outside the tire-box or furnace to the burning fuel, I surround the pipe 3 with an air pipe or cylinder 45, which, as shown, is

its inner periphery.

preferably open to deliver air only below the injected burning fuel and in front of the burner. This pipe or cylinder extends outside the fire-box or furnace and has its under end flared in order to secure a better suction of air into the fire-box.

IV hen my burner is used with the regulating means shown in Figs. VII to XIII, the secondary segmental or closure ring 19 is made of a sufliciently large segment to fully cover or close any space or opening which may be left between the ends of the flanges 13 13 of the parts or segments 13 13" of the segmental regulating-ring, so that there is no possibility of either oil or steam being emitted at the rear of the burner. This closure-ring 19, as shown, is provided with a vertical flange at As this flange extends up into the cavity of the steam-gage it prevents any steam from escaping backward when the steam-gage or sleeve 16 is raised or lowered to adjust or regulate the width of the steam outlet or discharge 17. y

In Figs. I and VII, I have shown the steam and oil connections and supplying-pipes. 47 represents a four-way connection, into one way of which the oil pipe 3. is screwed. The oilsupply pipe 48 enters the connection 47 from the bottom way. The steam-supply pipe 49 is connected with the upper way of this connection 47 and through pipes 50 and 51, union 52, L 53, collar 54, and the reducing- .)lug55, with the pipe 6 projecting through the way opposite the pipe 3. The pipes 50 and 51 are connected by the valve 55, which, as shown, is preferably provided in connection with the wheel 57 on the valve-stem 58, the wheel 57 being graduated, as shown.

A valve 59 is interposed in the pipe 49, by which the passage of steam through the nipple 60, connected with coupling 47 and open into the pipe 3, is controlled, thus forming means whereby steam may be blown through the pipe 3 to clean out the chamber 4 and d uct or outlet 9, if desired. The connection of the nipple 54 with the plug 55 is shown best in Fig. XVI, in which it is seen that the opening or way through the connection 47 opposite the pipe 3 is of a diameter just suflicient for the steam-pipe 6 and that a packing-gland 61 is provided, into which packing 62 is forced about the pipe 6, a washer 63 about the pipe separating the inner and outer layers of packing, being held in place by thc'reducing-plug 55, shown. The end of the pipe 6 screws into the collar 54.

In the steam-supply pipe 49, between the source of supply and the three-way connection 64, I interpose a steam-strainer, the construction of which is shown in detail in Fig. XV, Where it will be seen that the pipe 49 is connected with its continuation 49 by a union 65, preferably provided with a handle, whereby it may be turned. The chamber 66 is of slightly greater diameter than the diameter &

of the pipe 49, which, as shown, is provided with an annular flange 67, between which and the shoulder 68 a gasket (not shown) may be employed to insure a steam-tight joint. The strainer 69 is preferably of brass and with a dome top and slotted sides, the base-flange 70 being seated on the flange 67 of the pipe 49'. The end of the pipe 49 bears against the top face of this flange 70. The end of the pipe 49 preferably extends upward beyond the top of the flange 67 and into the bottom flange 70 of the strainer.

The operation is as follows: The valve 55 is operated to permit the passageof steam from the steam-supp] y pipe through the steampipe 6 and to permit it. to flowout through the ports 12 into the expansion-chamber 17 and thence through the steam-discharge slot 17. By terminating the sleeve between the outer channel or duct 9 and the expansivefluid supply the expansive fluid isallowed to begin to expand upward and away from the face of the top plate 7 before reaching the oil. This avoids excessive expansion of the expansive fluid against the body of oil in the channel or duct 9, so that the effect is more to suck off the surface of the oil as it rises in the channel, thereby in a measure vaporizing the oil from the outlet. The hollow stem being provided with radial'ports 12 directs the expansive fluid against the inner wall of the expansion-chamber or inner channel 17. The expansive fluid expands in this channel and is evenl distributed therein, so as to pass out evenly throughout all portions of the fluid-o utlet 17 By constructing the top plate 7 with a plane flat face of considerable width between the channel or duct 9 and the channel or expansion-chamber 17 and providing the sleeve 16 above the said face and terminating the outer periphery of the sleeve well within the surface of the said flat face an adjustable discharge-slot for the expansive fluid is provided, and the expansive fluid is directed across the outer channel or duct 9 in a plane parallel with the plane of the outer rim 2 of the body 2. By vertical adjustment of the sleeve 16 on the screw-threaded stem of the plug 8 the width of the slot 17 may be regulated as desired. After the valve 55 has been opened the valve in the oil-pipe 48 is opened and the supply of oil turned on. The oil rising'up through the oil-pipe 3, chamber 4:, into the channel or-duct 9 is carried out therefrom by the sheet of expansive fluid flowing across in a plane thereabove.

The flame produced by this burner may be readily regulated as desired and a very long narrow flame secured or a very wide flame with short projections. By suitably regulating the sleeve 16 the vertical body or depth of the flame may be regulated to suit the particular conditions under which the burner is used, and I have found that with this burner it is possible to secure a narrow short or very thick flame resembling more a ball of fire than the ordinary blast-flame secured by the majority of injector-burners. With the construction shown and described I. am able to avoid all carbonization on theburner and all tendency to clog with any of the minerals or impurities contained in the oil.

The air-pipe or cylinder 45, as shown, opens at the front end. and below the flame, and the heat of the burning atomizing-oil causes a suction through the pipe 45 and supplies the flame with the needed oxygen. 71 represents a flanged set-collar which I provide upon the pipe 3 beyond the flaring end of the pipe or cylinder 45. The flange 72 of this collar is of suflicient diameter so that by moving this collar into proximity with'the end of the pipe 45 or away therefrom the entrance of air into and the passage of air through the pipe 45 may be regulated as desired to secure the supply of requisite oxygen'to the burning atomizing liquid fuel. The air-chamber provided by the pipe or cylinder 45 surrounding the oil-pipe 3 prevents the furnace heat effectuating the carbonizatlon of the oil in the oilpipe 3 and prevents the heating of the oil to too great a degree. It is thus seen that l utilize the heat of the steam for superheating the oil and utilize the air passing through the cylinder 45 to prevent the furnace heat from heating the oil too hot.

If desired, the segmental ring 13 may be re moved, and a circular flame will then be produced.
